Applicants have created a method of constructing a wall to meet an applicable building code, and a wall created by this method. The method may include placing insulating concrete forms, having a cavity, where the wall is to be constructed; placing a limited quantity of metal reinforcement steel within the cavity, such that the limited quantity of reinforcing steel is insufficient to meet the applicable building code; pouring a mix of aggregate, sand, cement, fly ash, and mineral fibers into the cavity; and allowing the mix to cure, thereby meeting the applicable building code without additional metal reinforcement. The mix may contain between 40 and 50% stone, between 30 and 40% sand, between 10 and 15% Portland cement, between 5 and 10% fly ash, between 0.5 and 2% mineral fibers, and between 0.005 and 5% admixtures by weight. More specifically, the mix may contain between 45 and 50% stone, between 30 and 35% sand, between 10 and 12% Portland cement, between 5 and 8% fly ash, between 1 and 2% mineral fibers, and between 0 and 1% admixtures by weight. In one specific example, the mix may contain approximately 48.24% stone, 33.15% sand, 10.32% Portland cement, 6.88% fly ash, 1.41% mineral fibers, and preferably less than 0.005% of admixtures by weight. The mix may contain mineral fibers of different grades and/or dimensions.

Building code requirements typically require steel reinforcement, such as one half inch #4 rebar and/or five eighth inch #5 rebar depending on loads, in an Insulated Concrete Form (ICF) wall, irrespective of a thickness of concrete found in a center cavity of the ICF form. Without this traditional steel reinforcement in concrete building envelopes, an ICF wall system to not achieve building code requirements, especially during peak loading. Of course, inclusion of traditional steel reinforcement is costly, both in terms of materials and labor.

One relatively recent attempt to solve this problem is to replace some of the rebar with steel fiber. For example, Propex®'s Novamesh ICF mix design relies heavily on steel-fiber reinforcement to replace the structural strength achieved with traditional steel rebar reinforcement. Similarly to traditional steel rebar reinforcement, the steel fibers, when blended with concrete, are mechanically-bound within the hardened concrete matrix. The steel fibers provide the structural strength necessary to produce a concrete mix design with enough strength to meet building code requirements and/or American Society of Testing and Measures (ASTM) and/or American Concrete Institute (ACI) comparative tests. Consequently, the removal of steel-fiber reinforcement in the ICF building envelope would cause a Novamesh wall system to not develop enough strength during peak loading conditions to meet building code requirements. Additionally, the limited amount of polypropylene fibers found in the Novamesh ICF mix would not provide enough strength to, independently, provide the necessary structural reinforcement during peak loading conditions as the fibers are not actually structural fibers. Instead, the polypropylene fibers are included in the mix design to provide non-structural protection against shrinkage.

In addition, current steel fiber reinforcement has difficulty dispersing properly in the concrete matrix due to the “interlocking” nature of the steel fibers as they are blended. Since the fibers do not adequately disperse, it is questionable if the fibers are adequately distributed throughout the wall or consolidated within isolated regions of the wall. Sporadic placement of steel reinforcement would have significant structure implications for steel-fiber reinforced concrete. First, if an isolated wall section is void of steel fibers, this isolated section would be significantly weaker than intended. Second, if an isolated area of the wall experienced steel-fiber ‘balling’, this area would lack the quantity of cement binder necessary to mechanically fasten the steel fiber in place. In both cases, current steel fiber reinforcement may not meet building code requirements without expensive and time consuming installation practices.

In contrast, the mix design of the present invention uses minerals in place of steel-fibers to achieve the required strength needed to achieve building code requirements and/or ASTM and/or ACI approval for replacing traditional steel reinforcement in ICF wall systems. The use of minerals to replace steel reinforcement in ICF construction harnesses the synergistic relationship between unique combinations of natural occurring minerals, such as multiple lengths, thicknesses, compositions, and/or grades of mineral fibers, cement, and an industrial waste product, such as fly ash. In one preferred embodiment, the mineral fibers comprise a calcium inosilicate mineral (CaSiO₃) that may contain small amounts of iron, magnesium, and manganese. In other embodiments, the mineral fibers comprise one or more of the pyroxene group of minerals.

Rather than relying on mechanical bonding such as with steel rebar, steel fiber, and synthetic reinforcement for ICF construction, the mix design of the present invention relies on a chemical bond created through the unique combination of natural minerals, cement and fly ash. To put it another way, the bond which binds synthetic and steel fiber-reinforced concrete is mechanical, in that as the concrete dries, the fibers are bound in place, providing the required strength. In contrast, the mix design of the present invention relies on a chemical bond which is created during the concrete hydration process that fuses the materials together, creating a structural concrete matrix with enhanced reinforcement characteristics.

Along with considerable cost savings, removing steel reinforcement (rebar) and steel fiber reinforcement in ICF walls will dramatically improve the workability, consistency, strength and embodied energy of the concrete in ICF construction. Additionally, the elimination of steel reinforcement will allow for the reduction of labor to place and consolidate the fiber-filled concrete by eliminating the “balling” effect characterized by concrete with steel fiber reinforcement.

While others have used wollastonite in concrete mixtures for non-structural applications, these applications rely on a single grade, or length, of wollastonite and typically use 10% wollastonite per concrete volume, or greater. This use of mineral fibers, creates a concrete matrix with enhanced aesthetic attributes and reduced cosmetic cracking, which cannot meet structural building code requirements because such concrete mixes are simply not strong enough to be considered structural.

Furthermore, in our internal testing we discovered that combined grades of mineral fibers, when mixed with a high volume of fly ash, develops uncharacteristically-high flexural and axial strengths. In once embodiment, this uncharacteristically-high flexural and axial strength was exhibited in a mix containing only 1.41% mineral fibers by concrete volume. The chemical bonding, as opposed to traditional mechanical bonding, of the mix design of the present invention creates a finished structural wall system that exceeds building code requirements and/or ASTM and ACI testing standards, thereby allowing the mix design of the present invention to eliminate the need for most traditional steel reinforcement and all steel-fiber reinforcement. The mix design of the present invention, thus, meets both peak and post-peak strength requirements without the metal reinforcement previously needed.

The mix design of the present invention may also replace 40% of cement traditionally used with an industrial waste product, such as fly ash, rather than the common practice to only replace up to 20% of cement with fly ash. We believe that these higher levels of fly ash positively contribute to the chemical reactions and bonding taking place in the concrete hydration process. For example, we believe that pozzolons in the fly ash react with free calcium ions in the cement and mineral fibers enhancing the chemical bonding during the concrete hydration process.

We also believe that the ICF forms themselves provide optimal curing conditions that help improve the structural performance of the mix design of the present invention. For example, the chemical reactions may be enhanced because the concrete matrix cures within an insulated curing cavity. This cavity may help maintain a consistent temperature throughout the curing process. This cavity may also allow less water to escape during placement and curing. Both of these attributes would lead to enhanced structural characteristics. In comparison, ICF walls reinforced with steel fibers would not benefit from such optimal curing since the fiber-concrete bond is mechanical rather than chemical.

In one preferred embodiment, the mix design contains approximately 48.24% stone, or aggregate, 33.15% sand, 10.32% Portland cement, 6.88% fly ash, 1.41% minerals, and preferably less than 0.005% of admixtures by weight. However, a mix according to the present invention may contain between 30 and 50% stone, with a preferred range being between 40 and 50% stone. A mix according to the present invention may also contain between 30 and 50% sand, with a preferred range being between 30 and 40% sand. A mix according to the present invention may also contain between 5 and 20% Portland cement, with a preferred range being between 10 and 15% Portland cement. A mix according to the present invention may also contain between 2 and 15% fly ash, with a preferred range being between 5 and 10% fly ash. A mix according to the present invention may also contain between 0.5 and 10% minerals, with a preferred range being between 0.5 and 2% minerals. A mix according to the present invention may also contain between 0 and 10% admixtures, with a preferred range being between 0.005 and 5% admixtures. Thus, a preferred mix may contain between 40 and 50% stone, between 30 and 40% sand, between 10 and 15% Portland cement, between 5 and 10% fly ash, between 0.5 and 2% minerals, and between 0.005 and 5% admixtures. The lower end of the range represents the most commonly used percentage of the material and the upper bound is a measure that was determined, through our lab testing, to be unsuitable for this given application. An alternative mix may contain between 45 and 50% stone, between 30 and 35% sand, between 10 and 12% Portland cement, between 5 and 8% fly ash, between 1 and 2% minerals, and between 0 and 1% admixtures. Additional specific mixtures are shown below, along with the relative strength of a given cured wall for each mixture.

FIG. 1 is an illustration of a prior art reinforced wall built using traditional ICF techniques. As shown, forms 10 are filled with a traditional concrete mix 20 with traditional rebar reinforcement 30. FIG. 2 shows a traditional pattern of rebar 30 that may be needed to reinforce the concrete 20, in order to meet an applicable building code requirement.

FIG. 3 is an illustration of a reinforced wall 100 built using certain aspects of the present invention. As shown, the forms 10 are filled with a specially formulated concrete mix 120, such as that described above, with a limited quantity of traditional rebar reinforcement 30. When compared to FIG. 1, one can readily see that significantly less rebar 30 is required, in order to meet the applicable building code requirement. This results in dramatic cost savings, both in terms of labor and materials.

FIG. 4 shows an improved pattern of rebar 30 that may be all that is needed to reinforce the concrete 120. When compared to FIG. 2, one can readily see that significantly less rebar 30 is required. Rather than relying as heavily on the rebar 30, or other steel reinforcement, the reinforced wall 100 of the present invention relies on mineral fibers 140 and other components of the concrete mix of the present invention, as discussed above, in order to meet the applicable building code requirement.

Turning now to FIG. 5, a method of constructing a wall to meet an applicable building code according to certain aspects of the present invention will be described. A concrete mix 120 according to the present invention is prepared, as set forth in step A. The mix 120 of the present invention preferably includes mineral fibers and a relative high amount of fly ash. For example, 20-40% of the cement normally used in a traditional mix may be replaced with fly ash. As discussed above, the mix 120 may contain mineral fibers of different compositions, grades, and/or dimensions. This may result in significant material cost savings.

The forms 10 are set up, or placed, where the 110 is desired, as set forth in step B. A limited quantity of rebar 30, or other reinforcement, is placed in the forms 10, as set forth in step C. This limited quantity of metal reinforcement is insufficient to meet the applicable building code, as the reinforced wall 100 of the present invention does not rely slowly on the rebar 30, other metal reinforcement, or even mechanical bonding with the reinforcement, in order to meet the applicable building code requirement. This results in significant material cost savings.

The mix 120 is then poured into the forms 10, as set forth in step D. Because there is less rebar 30 in the voids within the forms, and because there is no need of metal fibers in the mix 120, the mix 120 flows relatively easily into the forms 110. Furthermore, because the mix 120 of the present invention is less susceptible to the clumping problems, or “balling” effect, associate with metal fibers in a more traditional mix, less effort is required to ensure proper distribution of the reinforcing materials. Finally, the mix 120 of the present invention is much easier on equipment, as there is no need of metal fibers in the mix 120 which can be damaging to mixing, as well as on-site, equipment. This results in significant labor and equipment cost savings.

Finally, the mix 120 is allowed to cure in the forms 10. As discussed above, the forms 10 provide a consistent temperature throughout the curing process and otherwise provides optimal curing, thereby enhancing the chemical reactions, thereby improving the structural performance of the mix 120 of the present invention. In this manner, the mix 120 of the present invention utilizes chemical bonding, rather than mechanical bonding, of the reinforcement material, such as the mineral fibers discussed above, in order to meet the applicable building code requirement with less metal reinforcement as previously required.

Other and further embodiments utilizing one or more aspects of the inventions described above can be devised without departing from the spirit of Applicant's invention. For example, while the present invention is anticipated to be ideal with four inch ICF walls, the method and/or mix of the present invention may be used with thinner or thicker walls, such as six or eight inch walls. Furthermore, while the invention is particularly well suited to ICF walls, the method and/or mix of the present invention may be used with other forms of concrete construction, such as cast-in-place or pre-cast walls, floors, and/or other panels or pavements. The method and/or mix of the present invention may also be used with tilt-up applications, such as where walls or other vertical elements are formed horizontally and then tilted-up vertically. Additionally, synthetic fibers may be used to supplement and/or replace some of the mineral fibers. Further, the various methods and embodiments of the present invention can be included in combination with each other to produce variations of the disclosed methods and embodiments. Discussion of singular elements can include plural elements and vice-versa.

The order of steps can occur in a variety of sequences unless otherwise specifically limited. The various steps described herein can be combined with other steps, interlineated with the stated steps, and/or split into multiple steps. For example, the wall 100 may be constructed in sections, each with their own iteration of one or more of the described steps. Additionally, or alternatively, the mix may be prepared while the forms are being placed, for example. Similarly, elements have been described functionally and can be embodied as separate components or can be combined into components having multiple functions.
